Your question is unfinished. If you are asking "how fast
is a rider traveling?", the answer is:
Circumference =(pi)d, =3.14 X 26, = 81.64 meters.
1 rotation every 4 minutes =81.64/ 4 = 20.4 m/min.
That's 67 ft./minute

angular velocity = w
w = 2 Ï / 4 radians / min
w = Ï / 2 radians / min
Linear speed = v
v = w r
v = Ï/2 x 13 ft / min
v = 20.4 ft / min
